In (a) a single 1344 × 1200 pixel image, from the “Mastcam right” camera (MSSS-MALIN) of the NASA Mars rover Curiosity, is shown together with a 300 × 336 pixel detail (b). We used 1064 raw images of 1344 × 1200 pixels from this camera (http://mars.jpl.nasa.gov/msl/multimedia/raw/) to find the average image (see 300 × 336 detail (c); the central part of that is shown as an extra inset) and the σ-image image (300 × 336 detail: (d)). Apart from the strong visibility of the Bayer pattern in the average image of this camera, a block of 3 × 5 pixels with a very poor response is marked by a white arrow in the various “detail” images. A smaller anomaly visible in both the average - and the standard deviation image is marked by another white arrow. The a posteriori corrected image is shown in panel (e) and in detail in (f). The Bayer pattern is now largely invisible as are the other marked anomalies. The improvement of Fourier Ring Correlation between different images of this dataset by the a posteriori correction is discussed in Fig. 4.
